Notes:
3-Oxy-1-azabicyclo[2.2.0]hexa-2,5-dienes (“3-oxy-1-Dewar-pyridines”) 6a-d, on cleavage of the enol ether or enol ester function, yield either 1-azabicyclo[2.2.0]hex-2-en-5-ones (“1-Dewar-pyridin-3-ones”) 9 or 2-azabicyclo[3.1.0]hex-2-en-4-ones 11, depending on the substituents and reaction conditions. Ester cleavage of 2-(benzoyloxy)-1-Dewar-pyridine 7a with methyllithium does not furnish a 1-Dewar-2-pyridinone, but a dimer thereof, namely the tricyclic compound 14.
